S-97690A152 4-40 x 7/16" ASME B18.6.3 Steel Pan Head Torx Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments
• Enhanced torque transmission and reduced cam-out thanks to the Torx T10 drive system for secure fastening
• Reliable mechanical strength with Rockwell B70 hardness, preventing stripping and deformation under load
• Broad compatibility and easy assembly from the coarse UNC 4-40 thread and Class 2A fit
• Streamlined installation in confined spaces with the low-profile, rounded pan head design
• Maximum grip and holding power due to the fully threaded 7/16" length for full engagement
• Professional black finish for part identification and a uniform, clean appearance

Professional Applications & Engineering Value

These zinc-plated steel Torx screws with a 4-40 UNC coarse thread are engineered to solve critical fastening challenges in industrial assembly. The combination of a rounded pan head and T10 drive provides a low-profile, high-torque solution that resists cam-out, reducing tool wear and assembly errors in automated or high-vibration environments like electronics enclosures, machinery, and automotive components. The fully threaded design ensures consistent clamping force along the entire 7/16" length, while the Rockwell B70 hardness offers dependable strength against shear and tensile stresses, making these industrial screws a robust choice for durable product construction.
